Question

The drawing shows box 1 resting on a table, with box 2 resting
ontop of box 1. A massless rope passes over a massless,
frictionlesspulley. One end of the rope is connected to box 2, and
the otherend is connected to box 3. The weights of the three boxes
areW1 = 53.0 N,W2 = 31.5 N,
andW3 = 29.0 N.Determine the magnitude of the
normal force that the table exertson box 1.
